This has never happened to me before. I have two devices. One is my rmbp and the other is a simple android phone. I was using my rmbp in my living with wifi connected and the cell phone everywhere around the house. I just brought my rmbp into the office space where the router is located along with my phone. The rmbp is still connected to the wifi, however the phone is not recognizing the signal. Under the phone setting it says, "not in the range" I have turned my phone on and off, re-set the wi fie and now under signal strength says " excellent ", hit "connetct" and it does not connect..... any trouble shoot idea ?
